When examining altered numerals on a check, an examiner should look for:
Answer: Overwriting, added strokes, or mismatched pen pressure in numeral areas
Altered numerals typically show added strokes, overwriting, or pen pressure inconsistencies that differ from the original writing.
Which of the following best defines 'eradication' as a document alteration method?
Answer: Bleaching out ink using chemical solvents
Eradication involves chemically removing ink from a document surface, often leaving detectable damage to paper fibers.
A forensic document examiner is asked to compare handwriting written 30 years apart from the same person. The main challenge is:
Answer: Natural aging may alter some writing characteristics while core habits remain
While aging can affect some features like tremor and letter size, fundamental habitual characteristics generally persist over decades.
In the context of forensic document examination, what is a 'disguised hand'?
Answer: Intentional alteration of one's natural handwriting to avoid identification
A disguised hand is when a writer deliberately modifies their natural writing style in an attempt to prevent identification.
Infrared luminescence examination of a document is particularly useful for:
Answer: Distinguishing between inks that appear identical under visible light
Different inks can fluoresce or absorb infrared light differently, revealing alterations or additions even when inks look identical to the naked eye.
When a document examiner concludes 'probable identification,' this means:
Answer: The evidence strongly suggests a common writer but falls short of absolute certainty
'Probable identification' indicates strong but not conclusive evidence that two writing samples originated from the same writer.
Which of the following alterations would be BEST detected using ultraviolet (UV) light examination?
Answer: Chemical erasures and paper surface disturbances invisible under white light
UV light causes damaged or chemically treated paper areas to fluoresce differently, making erased or chemically altered regions visible.
